M.2, formerly called Next Generation Form Factor (NGFF), is a specification for internal computer expansion cards and corresponding ports. Because of the smaller and more flexible dimensions associated with extended functions, M.2 is better suited for connecting e.g. SSDs - especially in compact devices such as ultrabooks or tablets.
The M.2 standard describes four PCI Express lanes and a SATA Revision 3.x (6 Gbps) port - all in one connector. At each port, both bus systems can also be used in parallel.
